TestNG Testing Skill

When to Use

Use this skill when you need generates TestNG tests in Java with groups, data providers, parallel execution, XML suite configuration, and listeners. Use when user mentions "TestNG", "@DataProvider", "testng.xml", "groups". Triggers on: "TestNG", "@DataProvider", "testng.xml", "TestNG suite", "parallel tests Java".

Examples are separate fragments: supply loginService/dashboard and the project AuthenticationException, import org.testng.asserts.SoftAssert and listener interfaces as needed. The three parallel suite lines are alternatives, not one valid XML document. Maven suite-property/report locations depend on the actual Surefire configuration; inspect pom.xml rather than assuming these commands configure it. Isolate test users/data and per-thread browser/service state before parallel execution, and close only resources created by the test. The listed reference/playbook.md is absent from this catalog copy.

Core Patterns
